Polyiso foam board is a highly versatile and popular insulation material used in a wide range of applications. Its exceptional thermal performance and excellent fire resistance make it an ideal choice for various building projects, including commercial and residential constructions. When considering insulation materials, one crucial factor to assess is the R-value. So, what exactly is the R-value of polyiso foam board?<\/p>\n

**The R-value of polyiso foam board is between R-5.7 and R-8 per inch of thickness.**<\/p>\n

Polyiso foam board is a type of rigid foam insulation made from polyisocyanurate, a closed-cell foam material. Its R-value measures its resistance to heat flow, indicating how effectively it can insulate a building from hot or cold temperature extremes. The higher the R-value, the better the insulation’s thermal resistance.<\/p>\n
